Be itknown that 1, PAUL FLEMMING, chemist, citizen of Germany. subject of the German Emperor, residing at llloorfurt-weg 1315, in the free town of Hamburg, in the State of Hamburg and Empire of Germany,

have invented new and useful lmprm'ements in Halogenphenolallnili Salts and Processes for the Manufacture of Same. of which the following is a specification.

Crystallized double compounds of phenol- .Alkali salts with phenol are known,'-and are produced by letting phenol, if desired in organic solvent media, act on alkalis, or salts with alkaline reaction. I have'found that it is possible in a similar mannerto produce complex halogenphenolalkali salts. This result was by no means to be foreseen as, on account of the presence of the'halogen it seemed probable that the reaction would take quite a different course. As a matter of fact the complex halogen phenolalkali salts produced by such methods are not compounded analogously to the corresponding complex phenolalkali salts. On the contrary the new substances (litter considerably both in chemical composition and also in part in physical qualities, especially solubility in water, from the compounds of the non-substituted phenols obtained by corre sponding methods. The new compounds are obtained by the method of treating halogenphenols or their homologues separately or in an organic solvent medium with alkalis, or salts with an alkaline reaction.

The new process is illustrated in a series of examples as follows:

Example 1: parts p-chloro-m-cresol are dissolved in approximately/1 0 parts of bone The new compounds obtained in this I Specification of Letters Patent.

manner possess the general composition a EOAllnyROH, wherein in and y indicate the number of molecules of lialogoi1pl1e1u' l.- alkali or free halogenphcnol and It the-halogenphenol compound used. With pot-assium salts especially, the compounds shown have the composition ROIQQROH or ROKll-OH. Vith sodium salts on the otherhand they have the composition QRONaROH. v

The new substances are remarkable for their great power-of disinfection and considerably surpassi'n effectiveness all hitherto known preparation -.of organic origin soluble in water, even" is preparations of halo gencresol soluble'in water'produccd by other methods, especially ofp-chloro-m-crcsol.

The new compounds are remark: ble when contrasted with the known complex salts of the phenols, further fortheir extraordinary readiness to dissolve in water, their good keeping qualities, and also the fact that, especially when in solution, they are almost odorless. The salts have an alkaline reac tion and when heated split off the chlorophenol which they contain.

Having now described my invention what I claim and desire to secure by Letters Patent of the United States is:

1. A process for the manufacture c1 halogenphenolalkali salts and'their homologues. which consists in treating member of the homologous series of which a halogen phenol is the lowest member with ga compound of alkali having an alkaline reaction, and isolating the complex salt which crystallizcs therefrom.

2. A. process for the manufacture of halogen;ihenolalkali salts and their homologues which consists in treating a member of the homologous series of which a halogenphcnol is the lowest member. in an organic solvent medium with an alkali and isolating the complex salt which crystallizes-therefrom. i

3. Halogenphenolalkali salts of the general composition wROAllm ROH where. a:

and having gpat power of disinfection and good lreepingf ialities.
